The 糖心产精国品免费入口*完整版accidents of 316L stainless steel plate 糖心产精国品免费入口*完整版 occurred frequently after using for about half a year. The causes of 糖心产精国品免费入口*完整版were analyzed by means of scanning electron microscope, energy spectrum analysis, metallographic examination, microhardness test and finite element simulation analysis. The results show that 糖心产精国品免费入口*完整版 cracking occurred in 316L stainless steel plate, resulting in leakage. Large residual tensile stress and Cl-
corrosion medium existed in the environment after cold working, leading to cracks and corrosion pits at the wave crest and valley with large 糖心产精国品免费入口*完整版, which were the main reason for the early cracking of plate. High temperature working environment accelerated the generation of pitting corrosion and the initiation and propagation of cracks, and finally the plate leaked.
